Parameters that affect the digging of a biologically-inspired underwater borrowing robot
(Massachusetts Institute of Technology, 2015)RoboClam 2 is a device that burrows based on the movement of the Atlantic razor clam. A functional RoboClam 2 has been built. Testing was conducted in a controlled laboratory environment to determine what parameters of the ... -
A parametric study of the repeatability of 3D printed LEGO®-like mechanical couplings
(Massachusetts Institute of Technology, 2017)Parts made using Additive Manufacturing (AM) are limited in size to the build area of the 3D printer being used. Embedded elastically averaged locators can be used to join AM parts into assemblies, resulting in a piece ... -
Part removal of 3D printed parts
(Massachusetts Institute of Technology, 2014)An experimental study was performed to understand the correlation between printing parameters in the FDM 3D printing process, and the force required to remove a part from the build platform of a 3D printing using a patent ... -
Passive microfluidic interconnects
(Massachusetts Institute of Technology, 2005)Equipment and procedures were developed to test two passive microfluidic interconnect rings held together by the friction forces on the contact surfaces. The second design forms fluid seals by means of thin flared rings ... -
Path control for robotic deburring
(Massachusetts Institute of Technology, 1984) -
A payload-centric approach towards resilient and robust electric-propulsion enabled constellation mission design
(Massachusetts Institute of Technology, 2017)Recent studies have shown that distributed spacecraft missions, or constellations, can offer similar performance to monolithic satellite missions for lower cost and less risk. Additionally, recent developments in and ... -
PCV valve flutter : vibration characterization through pressure and flow
(Massachusetts Institute of Technology, 2005)A Positive Crankcase Ventilation, or PCV, valve is required by internal combustion engines in order to regulate the flow of blow-by gases out of the crankcase and into the intake air stream. Fluctuations in the pressure ... -
Peak pressures due to steam bubble collapse-induced water hammer
(Massachusetts Institute of Technology, 1979) -
Peanut oil press for developing countries
(Massachusetts Institute of Technology, 2006)Despite the problems with obesity that the United States is facing today, malnutrition, caused in part by severely low dietary fat consumption, remains a problem among many people living in Sub-Saharan Africa. According ... -
Peanut oil press redesign for Developing countries
(Massachusetts Institute of Technology, 2007)One of the causes of malnutrition among the rural inhabitants of Sub-Saharan Africa is the high cost of dietary fats that are necessary to maintain normal body functions. Though the Food and Agriculture Organization of the ... -
Peluchi : product development of a programmable robotic toy to stimulate interest in the fields of science and technology amongst young girls
(Massachusetts Institute of Technology, 2011)Statistically speaking, science, technology, and engineering are male dominated fields. Peluchi is a second-generation prototype of a programmable robotic toy targeted towards young girls in hope of promoting more interest ... -
The performance of a diesel engine using benzol as a fuel,
(Massachusetts Institute of Technology, 1945) -
Performing overhead tasks with supernumerary robotic limbs
(Massachusetts Institute of Technology, 2014)Overhead tasks such as those frequently found in aircraft manufacturing pose health risks to the workers due to the strain imposed on the shoulders. To reduce the risk of injury, a set of supernumerary robotic limbs (SRL) ... -
pH control in a miniaturized bioreactor
(Massachusetts Institute of Technology, 2004)A miniaturized bioreactor with a volume on the order of 100 [micro]l has been built with the aim of increasing the efficiency of the screening process for various microbial cultures. Unlike larger reactors currently in ... -
Photographic lens manufacturing and production technologies
(Massachusetts Institute of Technology, 2011)An investigation was conducted to determine the methods and processes required for the manufacture of photographic objective lenses. Production of photographic lenses requires incredible precision in the melting, mixing, ... -
Photovoltaic cell efficiency at elevated temperatures
(Massachusetts Institute of Technology, 2010)In order to determine what type of photovoltaic solar cell could best be used in a thermoelectric photovoltaic hybrid power generator, we tested the change in efficiency due to higher temperatures of three types of solar ... -
Physical experimentation and actuated wheel design for granular locomotion using Resistive Force Theory
(Massachusetts Institute of Technology, 2016)Physical experiments were conducted using 3D printed wheels and a sand testing bed to explore the applications and predictive power of the Resistive Force Theory (RFT), an empirical model based on linear superposition ... -
Physical model of a hybrid electric drive train
(Massachusetts Institute of Technology, 2006)A motor and flywheel system was designed to simulate the dynamics of the electric drive train and inertial mass of a hybrid electric vehicle. The model will serve as a test bed for students in 2.672 to study the energy ... -
Physically modeling and mathematically simulating pressure transients in transfer lines
(Massachusetts Institute of Technology, 2008)Characterizing transient flow is not a trivial venture. It provides an excellent challenge for a senior mechanical engineering lab class. This project aimed at developing a new physical system for such a class based on the ... -
Planning and control for simulated robotic Sandia hand for the DARPA Robotic Challenge
